FUSE-IGNITER.

SPECIFICATION forming part of LettersPatent No. 651,939, dated June 19, 1900.

Application filed March 1 5, 1900. Serial No. 8,833. (No model.)

.To LEZ whom it may @0n/067117,: Y Y u Be it known that I, MAURICEO. SMITH, a citizen of the United States,residing at Springg field, in the county'of Sangamon and State of Illinois, have invented certain" new and useful Improvements in Fuse-Igniters, of which l the following is such a full, clear, and exact description as will enable others skilled in the art to which it appertains t0 make and use my said invention. i

My invention relates to devices adapted to contain combustible material, such as red fire, and provided with means for igniting same. n

The purposes of my 'invention are to provide a main structure of simple and convenientconstruct ion combini ngstability and portability and adapted to contain a suitable amount of combustible material, to provide simple and effective means for supporting ignitible fuses in proximity to the combustible material, to provide simple and effective means for igniting the fuses, to provide means for cutting the fuses to the desired length, and to provide means for the timely and quick 'release of the igniting device.

With these ends in view my invention consists of the novel features of construction and combinations of parts shown in the annexed drawings, to which reference is hereby made, and hereinafter particularly described, and recited inthe claims.

Referring to the drawings, Figure l isatop plan of the complete4 apparatus. Fig/2 is a vertical longitudinal section on the line 2 2 of Fig. l. Fig. 3 is avertical transverse section on the line 3 3 of Fig. l.

Similar letters of reference designate like A verging extensions d' u extend outwardly from one side of the box and at their juncture is An extenan upwardly-extending boss a2.

y sion d3 extends outwardly from the truncated side of the box and has at its outer extremity an upwardly-projecting boss a4. The extensions u.' and a3 and the bosses a2 and a4 are all preferably integral with the box A, as shown. A sweep B turns on a bolt B in the upper end of the stud 0,4 and oscillates horizontally above the box A. The sweepBhas at one extremity a hook b or equivalent device and at the other extremity afoot b'.

The under side of the foot b has a serrated or roughened surface which rubs on the heads of the fuses usable with the apparatus and ignites the fuses. One end of the foot b' is curved upward, so as to prevent the foot from striking too abruptly against 'and breaking off the heads ofthe fuses. A spring D has one en d secured to the boss a2 by a bolt or equivalent device and its other end suitably connected with the hook b. A lug a5 on the upper edge of the box A is pierced by a hole in which a pin U fits loosely, and the end of the pin enters a notch b2 in the edge of the foot b. When the sweep occupies the position shown in Figs. l and 3, the spring D is stretched and the pin C, engaging in the notch b2, locks thesweep against movement by the spring'. Upon the withdrawal of the pin O the spring lD reacts to quickly throw the sweep in the direction indicated by the arrow X.

l Projecting Aupwardly from the upper edge of one side of the box isY a lug afaced with acu'shion '0.7, of rubber or other yielding material.- The lug a6 serves to limit the throw of the sweep,and the cushion serves to prevent jar and noise'when the sweep stops against the lug.

The fuse-holder A is inside of and preferably integral with the box A and lies under and within the sweep of the foot b. Holes 0,8, adapted to receive fuses E, extend through the holder A and through the bottom of the box A. A plate A2, pivotally mounted on the under side of the box A, underlies the holes as and prevents the fuses from falling therethrough. One edge a9 of ltheplate A2 is a knife-edge and may be used to cut the fuses to the proper lengthV by inserting the fuses in the holes a8 and then turning the plate on its pivot, so as to cause the knife-edge to engage IOO with and cut off the lower parts of the fuses,

I claim as new, and desire to secure by'Letters which proglect bel-ow the bottom of the box.

A lug 0.10 on the plate A2 serves as a handle.

for turning the plate. l

When it is desired to clean the holes as, the

plate A2 may be turned, so as to uncover the holes and permit the contents thereof to'be pushed downward andout through'the holes.

From the foregoing it will be seen that the plate .A2 serves as a closure for the holes as and also as a knife for cutting the fuses to the proper length.

Inclined ways u. lead from the bottom of the box A to the holes as.

I prefer Vto use wax fuses tipped withful-l minate, as such fuses areconvenient to handle and do not break easily; but fuses of any;

.and the ways 0,11 are filled therewith. As the fuses burn down they ignite the material in the ways a11,and thence the iire spreads to the mass of'material .in the box A. Preparatory to igniting the fuses the sweep B is brought to the position shown in Fig. l, and the pin C is inserted vto temporarily retain the sweep in that position.. When all is in readiness, the sweep may be released by quickly withdrawing the 'pin C. This is preferably accomplished by means of a thread or wire fine enough to be not `easily visible ata distancesay ten paces from the apparatus. One end of the thread or wire is secured to the Leye of the pin', andthe operator jerks the-thread or wire to withdraw the pin. When the'pin is withdrawn, the spring D reacts to throwthe sweep 'quickly to theV position indicated by dotted lines in Fig. 1, i-n which position it comes to rest with the edge of the sweep in contact with the cushion a7. During this movement of the sweep the shoe b rubs on the t-op of and ignites the fuses, causing them to set on fire the combustible material con` tained in the box A.

Having fully described my invention, what 1. V In a fuseeigniter, the combination of a sweep having a serrated and upturned foot, a box above which said sweep is oscillative,

a fuse-holder adapted to support fuses inposition tobe engaged by the serrations on foot of said sweep, and means for operating said sweep, substantially as se't forth.

, Y2. In a fuse-igniter, the combination of a box adapted to contain combustible material;

a fuse-holder within said box, having holes for fuses and ways leading to said holes; and

' a sweep having a serrated and upturned foot andoscillative above said fuse-holder, as set forth.

3. In a fuse-igniter the combinationof a box, a fuse-holder integral withl said box and having holes extending therethrough, and a combinedcutter and closure having a knifeedge"andmounted on said box contiguous to the holes through the fuse-holder as set forth.

4.' In a fuse-igniter, the combination of a -sweep having a serratedand upturned foot, a box'a'bove which said sweep is oscillati-ve,

- a' fuse-holder adapted to support'fuses in position to be engaged bythe serratons on the foot of said sweep, a spring actuatingsaid sweep and means for engaging and disengaging said sweep, as set forth.

5. In a fuse-igniter, the combinationof a notched sweep having a serrated and up .turned foot, a. box above which 'said sweep oscillates, a fuse-holder adapted to support fuses in position to be engaged bythe serrations onthe foot of said-sweep, a Yspring a'ctuating said sweep,` and `a pin on said box' engaging inthe notch-,in said sweep ,as set forth.

6. In a fuse-igniter the combination of a box, a' sweep oscillative above said box, a spring actuating said sweep, means for setting and releasing said Vsweep and a lug on's'aid box limiting the movement ofV said sweep, as set forth.

In 4witness whereof Ihave hereunto subscribed my name, at Springfield, Illinois,rthis lth'day of-February, A. D. 1900.
